112-1205E 25.4 mm Dia. x -50 mm FL; Uncoated; Plano-Concave Lens

The 112-1205E is a Plano-Concave Lens with a diameter of 25.4 mm and a focal length of -50 mm, making it a negatively powered lens. This lens is sourced from EKSMA Optics, a reputable vendor in the optical components industry. The lens is uncoated, which means it does not have any additional layers to protect it from environmental factors or to enhance its optical properties.

The lens's geometry is characterized by its diameter, thickness edge, and thickness center. The diameter is 25.4 mm, the thickness edge is 5.5 mm, and the thickness center is 1.9 mm. The radii of curvature are -23.8 mm for the first surface and 0 mm for the second surface, indicating a plano surface. The lens's inner and outer radii are both 0 mm, further emphasizing its planar nature.

The lens is made from UVFS MAL-1965, a material with a refractive index suitable for use in the ultraviolet region of the spectrum, specifically at a wavelength of 355 nm. The lens's shape is spherical, which is the most common type of lens shape due to its ease of manufacturing and versatility.
